Though this data seems innocent enough, when it's put together it can tell a whole lot about your health, finances and behavior. That information, researchers remind us, could eventually be used against you.

By using lenses and software, the recorded information can be turned into a proper image. Human vision is an ordinary process: the use of two eyes (and a powerful brain that processes visual information) provides human observers with a sense of depth perception. But how does a video camera attached to a robot "see" in three dimensions?

These micro and nano structures must be manufactured and assembled with the highest precision so that in the end, the overall system will function smoothly. Scientists have now developed a metrological scanning probe microscope into a micro and nano coordinate measuring instrument. This now allows dimensional quantities with nanometer resolution also to be measured on three-dimensional objects in an extraordinarily large measurement range of 25 mm x 25 mm x 5 mm.
